Today as an old brandYonghengshengBlister machinery manufacturers, to introduce to youWhat is the blister temperature of PET and PVC sheets in general?
Blister temperature of PET and PVC sheet in general:
1, PVC: due to the poor thermal stability of PVC, long-term heating will lead to decomposition, release HCL gas, so that PVC discoloration, so its application range is narrow, the use temperature is generally between 15~55 degrees.
2, PET:PET thermal deformation temperature of 80~82 degrees, the color and non-transparent film added color masterbatch and additives, will affect the thermal deformation temperature of the sheet, can be adjusted according to the specific situation.
Blister molding technology: plastic sheet (plate) material thermoforming processing technology, is a plastic secondary processing industry technology. It is different from one-time processing technology such as injection molding and extrusion. It is not for heating and molding plastic resin or particles or continuous molding with the same section through the same die. Nor is it using machine tools, cutting tools and other mechanical processing means to cut off a part of the plastic material to obtain the required shape and size, but for the plastic sheet (plate) material, heating and using the mold, vacuum or pressure to the sheet (plate) material deformation, to achieve the required shape and size, supplemented by supporting processes, to achieve the purpose of application.
Blister molding equipment including clamping system, heating system, vacuum and compressed air system and molding mold and other parts.
